1.1 This specification is for an oil-flooded rotary screw compressor with a minimumcapacity of 1255 CFM (measured in accordance with CAGI-PNEUROP Test CodePN2CPTC2) at a full load pressure rating of 125 PSIG. This compressor shall be capableof full load operation at 125 PSIG and have a maximum pressure capability of 140 PSIG.

A) Constant Run Mode -- This method shall allow the operator to set anoperating pressure range within which the compressor will adjust its capacity tosatisfy the system demand or unload during periods of no demand. B) Auto Dual Mode -- This method shall allow the operator to set an operatingpressure range within which the compressor will adjust its capacity to satisfy thesystem demand or unload during periods of no demand. After a user-definedperiod of unloaded operation, the compressor will automatically shutdown andassume a standby mode. Should system demand return, the compressor willautomatically restart. C) Network Mode -- In place of the pressure deadband, the Network Mode shalluse a target pressure and a variable response rate. The control shall maintain thesystem pressure to within two or three pounds of the target pressure. In the upper50% of the capacity range, the control shall match system demand without

restricting the inlet air flow. In the lower 50% of the capacity range, the controlshall select either a load/no load or modulating control method, based onuser-defined parameters.
